any opinions on the DC solicitations for October?

Somehow this month I have a hard time deciding which new (mini-)series are worth giving a try. I probably should wait until this stuff is actually published when in doubt, so that I can take a look at the comic or maybe read reviews, but my store doesn't always order a huge surplus number of all these series.

In particular I'm wondering what you think about the Outsiders relaunch as Batman and the Outsiders (written by Tony Bedard), the Gotham Underground mini-series (written by Frank Tieri), and that Simon Dark series by Steve Niles and Scott Hampton.

I'm also waffling about getting this Crime Bible: The Five Lessons of Blood mini-series by Greg Rucka. I mean, I like his writing more often than not, but the blurb kind of confuses me on what this is about, maybe because I'm still lagging so far behind with the current DC events?

Any opinions on these? Predictions or tea leave readings on their likely readability? Any other thoughts on DC's October solicitations? Like, what is it with this bazillion of Countdown tie-in mini-series, anyway?
